The left intercostal space between rib 6 and 7 and the paraspinal musculature (rhomboids major, spinalis thoracis, longissimus thoracis, iliocostalis thoracis, multifidus thoracis) from T4 to the iliac crest were tender to palpation with increased myofascial tension, especially on the left.
The spinal extensors: deep muscles--erector spinae: spinalis, longissimus, iliocostalis, which inserts between the spinous and the transverse processes, its main role being to hold up the spine and ensure its stability; intermediate muscles: serratus posterior superior, serratus posterior inferior; superficial muscles: rhomboideus minor; these muscles are responsible for the movement.

The upper erector spinae consist of the thoracic fibres of iliocostalis lumborum and longissimus thoracis.
Extension in the lumbar spine is produced by the superficial erector spinae muscle group, longissimus thoracis pars lumborum and iliocostalis lumborum pars lumborum, and by the superficial fibers of the multifidi muscles.
